Item 1 - Review of Minutes
Duncan Silver suggested that the presentation of the roadway
width data could be clearer. It is possible that someone
could interpret it to mean an l8-foot pavement width, which
is not the case.
Item 2 - Draft Traffic Forecast Technical Memorandum
A draft of the safety technical memorandum was distributed
and Cliff Forsgren briefly explained the memorandum. The
fundamental conclusion stated in the memorandum is that
there are accidents occurring in Logan Canyon at a greater
rate than the' average for similar roads in the state, but
that the accidents are not generally serious. In the memo­randum,
it is recommended that during the alternative devel­opment
portion of the study, safety related alternatives be
considered at locations identified.
Lynn Zollinger suggested that the original accident reports
should be reviewed in order to better define the location
and cause of the accidents. Duncan Silver suggested that it
was probably not necessary to go into greater detail except
for specific improvements.
Duncan asked that a day/night breakdown of accidents be in­cluded
in the memorandum. Bill Helm thought that it would
be helpful to expand Table 6 to include the number of each
type of accident (severity 1 through 5). Duncan also pointed
out that roadway improvements to not often reduce the number
of accidents, but will reduce the severity.

Steve Flint asked what effect the latest safety improvements
had on the accident rate. Duncan pointed out that since the
safety project had been completed within the past few months,
it -would not be possible to estimate the impact, with any
degree of confidence, for 3 or 4 years. There was some dis­cussion
about the chevrons which had been placed to mark one
particularly sharp curve, and whether they had improved the
safety of that curve. No one was certain when the chevrons
were installed so that question could not be answered at
the meeting.
Duncan also suggested that something be said about the number
of accidents which may be occurring during peak traffic pe­riods.
Steve Flint asked for copies of the "quick list".
Cliff will see that he gets copies.
Item 3 - Review of Manual Traffic Counts
The date of the first public information meeting was set for
September 23, 1986. Duncan Silver suggested that we should
take the opportunity at the meeting to ask questions. ""How
long does it take you to get through the Canyon now?" "How
much faster do you want to get through the Canyon?" "What
are you willing to give up to get through that fast?"
Bill Helm said that it might be helpful if there was an op­portunity
to discuss the types of improvements that might be
necessary to upgrade the road or eliminate some problems.
The public would then have an idea of what might happen if
some types of improvements were implemented.
The next ID team meeting was scheduled for September 22,
1986 at 3:00 p.m. at the District Office in Ogden.
